Description

Technical Field

[0001] This utility model belongs to the field of mining equipment, and in particular relates to a self-moving device for mining following cables. Background Technology

[0002] Tunnel boring machines and coal loading machines are key equipment used in the core process of "rock breaking / coal breaking-loading" in underground engineering such as mines and tunnels. The two are complementary in function and are often used together, but they have significant differences in applicable scenarios, core functions and structural design.

[0003] The cables of tunneling machines and coal loading machines are the "energy and signal transmission hubs" for equipment operation. Their core functions fall into two categories: First, power transmission. Both are high-power electric devices, and the cables need to stably transmit high-voltage electrical energy (such as 6kV / 10kV) underground to the motors to drive the traveling mechanisms (tracks / rail wheels), working parts (tunneling machine cutting head, coal loading machine bucket / rake bucket), and auxiliary systems (conveyors, hydraulic pumps) to ensure the realization of core actions such as rock breaking and loading. Second, signal transmission. The cables can transmit control signals (such as instructions from the control panel for cutting speed and loading angle) and monitoring signals (equipment temperature, fault warnings, location information, etc.) to ensure that operators can monitor the equipment status in real time and operate it accurately. At the same time, some cables also have explosion-proof and crush-resistant characteristics to adapt to the complex underground environment and ensure safe operation.

[0004] During the operation of tunneling machines and coal loading machines, it is necessary to arrange for dedicated personnel to pull and move the cables in real time. However, the high concentration of coal dust during operation results in extremely low visibility. This not only makes it easy for the equipment to be affected by untimely pulling and moving, but also poses a safety hazard of accidental injury to people by the tunneling machine, thus restricting the efficiency of operation and the level of safety management. Utility Model Content

[0005] The purpose of this invention is to provide a self-moving device for mining follow-up cables to solve the problems of low efficiency and safety hazards associated with manual cable pulling in real time.

[0006] The present invention adopts the following technical solution: a mining follow-up cable self-moving device, the self-moving device is set close to the tunneling machine or coal loading machine and located behind the tunneling machine or coal loading machine;

[0007] The self-moving device includes:

[0008] The top fixing rod is horizontally installed along the direction of the roadway and close to the top of the roadway. Multiple fixing bolts are fixedly connected to its upper part along its direction. Each fixing bolt is used for the steel wire rope to pass through in sequence. The front end of the steel wire rope is connected to the tail end of the tunneling machine or coal loading machine, while the rear end of the steel wire rope is fixed to the anchor net at the top of the roadway, thereby suspending the top fixing rod at the top of the roadway.

[0009] The sliding shell is horizontally installed along the direction of the tunnel and located at the lower end of the top fixing rod. Its top is fixedly connected to the lower side of the top fixing rod. The sliding shell is a hollow strip shell with openings at the front and back, and its bottom has an overlapping groove through its direction.

[0010] Multiple support mechanisms pass through the front opening of the sliding housing and extend into the inner cavity of the sliding housing. Each support mechanism can slide back and forth along the inner cavity of the sliding housing. The lower end of each support mechanism carries the cable of the tunneling machine or coal loading machine, so that the support mechanism also slides forward as the cable is pulled forward by the tunneling machine or coal loading machine, thereby allowing the tunneling machine or coal loading machine to pull the cable in real time.

[0011] The beneficial effects of this utility model are:

[0012] This invention can replace manual labor by using a load-bearing mechanism to enable the cable to move automatically and synchronously with the equipment, completely replacing manual pulling and moving, and fundamentally solving the safety hazards of manual operation in high-dust environments.

[0013] The bearing mechanism of this utility model can slide back and forth along the inner cavity of the sliding housing, avoiding excessive stretching or loosening of the cable and ensuring the stability of cable operation.

[0014] When the wire rope of this utility model passes through the fixing bolt, the two ends of the wire rope near the fixing bolt are fixed with rope clamps, thereby preventing the cable from driving the top fixing rod to move back and forth along the wire rope. When it is necessary to move the entire self-moving device forward, the rope clamps can be removed. The installation and disassembly are convenient, and it is suitable for complex underground roadway environments. No complicated auxiliary equipment is required, which facilitates rapid deployment and maintenance on site. Attached Figure Description

[0018] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0019] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "multiple" means two or more. The term "orientation" in this utility model refers to the orientation of the utility model within the... Figure 1 Description of the state's progression.

[0020] This utility model discloses a self-moving device for mining following cables, such as... Figure 1 and Figure 2 As shown, the self-moving device is installed close to the tunneling machine or coal loading machine and located behind the tunneling machine or coal loading machine.

[0021] The self-moving device includes: a top fixing rod 10, a sliding housing 12, and multiple load-bearing mechanisms.

[0022] The top fixing rod 10 is horizontal and installed along the direction of the roadway and close to the top of the roadway. Multiple fixing bolts 11 are fixedly connected to the upper part of the top fixing rod 10 along its direction. Each fixing bolt 11 is used for the wire rope to pass through in sequence, so that the front end of the wire rope is connected to the tail of the tunneling machine or coal loading machine, while the rear end of the wire rope is fixed to the anchor net at the top of the roadway, thereby suspending the top fixing rod 10 at the top of the roadway.

[0023] The sliding housing 12 is horizontally arranged along the direction of the tunnel. The sliding housing 12 is located at the lower end of the top fixing rod 10. The top of the sliding housing 12 is fixedly connected to the lower side of the top fixing rod 10. The sliding housing 12 is a hollow strip-shaped housing with openings at the front and back. The bottom of the sliding housing 12 is provided with an overlapping groove 13 through its direction.

[0024] Multiple support mechanisms pass through the front opening of the sliding housing 12 and extend into the inner cavity of the sliding housing 12. Each support mechanism can slide back and forth along the inner cavity of the sliding housing 12. The lower end of each support mechanism carries the cable of the tunneling machine or coal loading machine, so that the support mechanism also slides forward as the cable is pulled forward by the tunneling machine or coal loading machine, thereby allowing the tunneling machine or coal loading machine to pull the cable in real time.

[0025] The load-bearing mechanism includes: two rolling wheels 14, a load-bearing rod 15, a suspension ring 16, and a load-bearing ring 17.

[0026] Two rolling wheels 14 are located on the left and right sides respectively; the two rolling wheels 14 are respectively attached to the inner cavity of the sliding housing 12 through the overlapping groove 13.

[0027] The support rod 15 is set horizontally, and its two ends are rotatably connected to two rolling wheels 14 respectively.

[0028] The upper end of the suspension ring 16 is fitted onto the middle of the bearing rod 15, and the lower end of the suspension ring 16 extends downward.

[0029] The bearing ring 17 is located below the suspension ring 16. The bearing ring 17 is sleeved on the lower end of the suspension ring 16. The bearing ring 17 is a closed structure, and its inner cavity is used for the cable to pass through.

[0030] The fixing bolt 11 of this utility model is a ring structure with a central hole for the steel wire rope to pass through. The cross-section of the sliding housing 12 in this utility model is rectangular or square, and the two rolling wheels 14 are respectively placed on both sides of the bottom of the sliding housing 12, so that the two rolling wheels 14 can slide back and forth in the inner cavity of the sliding housing 12 along the direction of the sliding housing 12. This makes it easier for the cable to pull the bearing ring 17, the suspension ring 16, and the bearing rod 15 in sequence after being subjected to forward tension, thereby pulling the two rolling wheels 14 to roll, thus preventing the cable from being too loose or too tight.

[0031] Regarding the selection of materials, the sliding housing 12 can be made of welded steel plate, and the suspension ring 16 can be modified using turnbuckles. When the cable passes through the bearing ring 17, the cable and the bearing ring 17 can be fixed together to ensure that the cable length between the two bearing rings 17 is equal, avoiding the cable being too tight between two adjacent bearing rings 17 and too loose between two other adjacent bearing rings 17. For the setting of the fixing bolt 11, it is preferable to set one fixing ring 11 every 2 meters. The front end of the wire rope near the working face is connected to the tail of the tunneling machine or coal loading machine, and the rear end of the wire rope is anchored to the top of the roadway, thereby realizing the synchronous linkage of the cable with the movement of the equipment.

[0032] Using this utility model can reduce the number of dedicated cable movers by one, thereby lowering labor costs. At the same time, it completely eliminates the problem of cable movement delay caused by coal dust environment, avoids the risk of tunneling machine accidents, and indirectly reduces the economic losses caused by safety accidents.

[0033] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
